Kylie Jenner is reportedly going to get hitched to boyfriend Tyga after she turns 18 in August. Meanwhile, the rapper's grandmother gave her stamp of approval for the "KUWTK" star.

"Kylie Jenner is on the fast track to the wedding chapel! Amid reports that she and Tyga are already engaged, the reality star reportedly wants to get married 'as soon as she turns 18 in August,'" said OK! magazine.

"Kylie accepted Tyga's proposal a few weeks ago and made the announcement to her family," a source told In Touch Weekly, according to Radar Online.

Kylie Jenner reportedly couldn't wait to marry Tyga.

"She told her friends that Tyga gave her a 'symbolic ring' for now and she isn't showing anyone until her birthday, when she'll make an official announcement... They're tired of hiding," the source claimed.

Speaking to Daily Mail, Kim Nguyen, 70, said, "We all love Kylie and think she is so much better for Tyga than Blac."

"Yes she is King's mum, but Blac just wasn't a very nice person and Kylie comes from a much better family.She is such a sweet, lovely girl and seems to adore Tyga," she added. "So we didn't mind him splitting up from Blac. It was a relief for us all."

Blac Chyna is reportedly planning to file sole custody claims on their son King Cairo as she will allegedly use Tyga's relationship with Kylie Jenner as proof that he shouldn't be a good model.

A source told Hollywood Life, "She feels humiliated that he chose Kylie over her. That's devastating and something she's going to struggle with for a very long time."

"She wants her old life with Tyga back - she wants them to be a family again, but she knows he's on a different page. Every time she calls him out on social media, it's because she's hurting inside and wants him to feel her pain," the source added of Blac Chyna's custody claims.
